Problem Definition

The context for custom fields can be deleted without confirmation.

Suggested Solution

In the delete button highlighted in the image below, add a confirmation that the existing data of the context will be deleted.

Why this is important

This is a serious concern on the reliability as it's possible to delete something without confirmation. There is a chance to click in the cog icon to edit the context and click on the bin and delete it accidentally.
If you have for example a custom field with multiple preset values, if the context is deleted, you must recreate the context and edit all issues accordingly.

Workaround

None.
